The Mariakapel (Mary Chapel) was built in the years 1954-1957 using medieval building materials. The bricks are from the foundations of an old monastery and the roof beams are from an old Saxon farmhouse. Money, volunteer labour and design were provided by the local community of Borne.

The chapel is 6 metres wide, 4 metres deep and 8.5 metres high. On either side is a stained-glass window. The statue of Mary, carved from sandstone, came from Vreden in Germany, where it had been found in pieces near a bombed-out church. It has been fully restored and provided with head and feet. Borne's Mariakapel is considered being one of the most beautiful in the region.

In september 1957, the chapel and the statue of Mary were consecrated.
